CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No.PCT/CN2019/076880, filed Mar. 4, 2019, claims the priority benefit ofChinese Patent Application No. 201810200891.3, filed on Mar. 12, 2018,the full disclosure of which is incorporated herein by reference.

BACKGROUND Technical Field

The present disclosure relates to methods and devices in wirelesscommunication systems, and in particular to a method and a device in awireless communication system that supports multi-antenna transmission.

Related Art

Massive Multi-Input Multi-Output (MIMO) becomes a hot topic whenstudying next generation mobile communications. For the massive MIMO,multiple antennas based on beamforming form a narrow beam which pointsto a particular direction to improve the quality of communication. Sincea beam formed by beamforming of multiple antennas is usually narrow,beams from a base station and a User Equipment (UE) need to be alignedfor effective communications. When beams of a base station and a UE areout of synchronization due to a blocking or a UE movement, that is, theyare not aligned, the communication quality between the two will begreatly declined or even the two are unable to communicate.

Multiple Transmitter Receiver Points (TRP) can serve a UE simultaneouslyso as to improve robustness of communication and transmission rate of asingle UE. A UE uses different beams to align beams from different TRPsto form multiple beam pairs. The plurality of beam pairs may transmitsame data to improve communication reliability of the UE, or maytransmit varied data to enhance the throughput of the UE.

SUMMARY

The inventors have found through researches that in the case of multipleTRPs serving a UE at the same time, uplink transmission for multipleTRPs needs to be transmitted with a correct beamforming vector to ensurethat it can be received correctly by a corresponding TRP. When uplinkdata and uplink control information for different TRPs conflict in timedomain, whether the uplink control information for another TRP can becarried on a physical layer data channel for one TRP needs to bedetermined according to transmitting beams of two TRPs; otherwise, areception of the uplink control information will fail, or an extra delayis incurred due to the uplink control information needs to betransmitted from one TRP to another TRP.

In view of the above problem, the present disclosure provides asolution. It should be noted that although the initial motivation of thepresent disclosure is for multi-TRP transmission, the present disclosureis also applicable to single-TRP transmission.

Embodiment 3

FIG. 3 is a schematic diagram illustrating a radio protocol architectureof a user plane and a control plane. In FIG. 3, the radio protocolarchitecture for a UE and a gNB is represented by three layers, whichare a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1)is the lowest layer and performs signal processing functions of variousPHY layers. The L1 is called PHY 301 in the present disclosure. Thelayer 2 (L2) 305 is above the PHY 301, and is in charge of the linkbetween the UE and the gNB via the PHY 301. In the user plane, L2 305comprises a Medium Access Control (MAC) sublayer 302, a Radio LinkControl (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP)sublayer 304. All the three sublayers terminate at the gNBs of thenetwork side. Although not described in FIG. 3, the UE may compriseseveral protocol layers above the L2 305, such as a network layer (i.e.,IP layer) terminated at a P-GW 213 of the network side and anapplication layer terminated at the other side of the connection (i.e.,a peer UE, a server, etc.). The PDCP sublayer 304 provides multiplexingamong variable radio bearers and logical channels. The PDCP sublayer 304also provides a header compression for a higher-layer packet so as toreduce a radio transmission overhead. The PDCP sublayer 304 providessecurity by encrypting a packet and provides support for UE handoverbetween gNBs. The RLC sublayer 303 provides segmentation andreassembling of a higher-layer packet, retransmission of a lost packet,and reordering of a packet so as to compensate the disordered receivingcaused by Hybrid Automatic Repeat reQuest (HARQ).

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a New Radio (NR) nodeand a UE, as shown in FIG. 4. FIG. 4 is a block diagram illustrating aUE 450 and a gNB 410 that are in communication with each other in accessnetwork.

The gNB 410 comprises a controller/processor 475, a memory 476, areceiving processor 470, a transmitting processor 416, a multi-antennareceiving processor 472, a multi-antenna transmitting processor 471, atransmitter/receiver 418 and an antenna 420.

The UE 450 comprises a controller/processor 459, a memory 460, a datasource 467, a transmitting processor 468, a receiving processor 456, amulti-antenna transmitting processor 457, a multi-antenna receivingprocessor 458, a transmitter/receiver 454 and an antenna 452.

In downlink (DL) transmission, at the gNB 410, a higher-layer packetfrom a core network is provided to the controller/processor 475. Thecontroller/processor 475 provides a function of the L2 layer. In DLtransmission, the controller/processor 475 provides header compression,encryption, packet segmentation and reordering, and multiplexing betweena logical channel and a transport channel, and radio resource allocationfor the UE 450 based on various priorities. The controller/processor 475is also in charge of HARQ operation, retransmission of a lost packet,and a signaling to the UE 450. The transmitting processor 416 and themulti-antenna transmitting processor 471 perform various signalprocessing functions used for the L1 layer (that is, PHY). Thetransmitting processor 416 performs coding and interleaving so as toensure an FEC (Forward Error Correction) at the UE 450 side, and themapping to signal clusters corresponding to each modulation scheme(i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmittingprocessor 471 performs digital spatial precoding on the encoded andmodulated symbols, including codebook-based precoding andnon-codebook-based precoding, and beamforming processing to generate oneor more spatial streams. The transmitting processor 416 then maps eachspatial stream into a subcarrier. The mapped symbols are multiplexedwith a reference signal (i.e., pilot frequency) in time domain and/orfrequency domain, and then they are assembled through Inverse FastFourier Transform (IFFT) to generate a physical channel carryingtime-domain multi-carrier symbol streams. After that the multi-antennatransmitting processor 471 performs transmission analogprecoding/beamforming on the time-domain multi-carrier symbol streams.Each transmitter 418 converts a baseband multicarrier symbol streamprovided by the multi-antenna transmitting processor 471 into a radiofrequency (RF) stream. Each radio frequency stream is later provided todifferent antennas 420.

In downlink (DL) transmission, at the UE 450, each receiver 454 receivesa signal via a corresponding antenna 452. Each receiver 454 recoversinformation modulated to the RF carrier, converts the radio frequencystream into a baseband multicarrier symbol stream to be provided to thereceiving processor 456. The receiving processor 456 and themulti-antenna receiving processor 458 perform signal processingfunctions of the L1 layer. The multi-antenna receiving processor 458performs receiving analog precoding/beamforming on a basebandmulticarrier symbol stream from the receiver 454. The receivingprocessor 456 converts the baseband multicarrier symbol stream afterreceiving the analog precoding/beamforming from time domain intofrequency domain using FFT. In frequency domain, a physical layer datasignal and a reference signal are de-multiplexed by the receivingprocessor 456, wherein the reference signal is used for channelestimation, while the data signal is subjected to multi-antennadetection in the multi-antenna receiving processor 458 to recover any UE450-targeted spatial stream. Symbols on each spatial stream aredemodulated and recovered in the receiving processor 456 to generate asoft decision. Then the receiving processor 456 decodes andde-interleaves the soft decision to recover the higher-layer data andcontrol signal transmitted on the physical channel by the gNB 410. Next,the higher-layer data and control signal are provided to thecontroller/processor 459. The controller/processor 459 performsfunctions of the L2 layer. The controller/processor 459 can be connectedto a memory 460 that stores program code and data. The memory 460 can becalled a computer readable medium. In downlink transmission, thecontroller/processor 459 provides demultiplexing between a transportchannel and a logical channel, packet reassembling, decryption, headerdecompression and control signal processing so as to recover ahigher-layer packet from the core network. The higher-layer packet islater provided to all protocol layers above the L2 layer, or variouscontrol signals can be provided to the L3 layer for processing. Thecontroller/processor 459 also performs error detection using ACK and/orNACK protocols as a way to support HARQ operation.

In uplink (UL) transmission, at the UE 450, the data source 467 isconfigured to provide a higher-layer packet to the controller/processor459. The data source 467 represents all protocol layers above the L2layer. Similar to a transmitting function of the gNB 410 described in DLtransmission, the controller/processor 459 performs header compression,encryption, packet segmentation and reordering, and multiplexing betweena logical channel and a transport channel based on radio resourceallocation of the gNB 410 so as to provide the L2 layer functions usedfor the user plane and the control plane. The controller/processor 459is also responsible for HARQ operation, retransmission of a lost packet,and a signaling to the gNB 410. The transmitting processor 468 performsmodulation mapping and channel coding. The multi-antenna transmittingprocessor 457 implements digital multi-antenna spatial precoding,including codebook-based precoding and non-codebook-based precoding, aswell as beamforming. Following that, the generated spatial streams aremodulated into multicarrier/single-carrier symbol streams by thetransmitting processor 468, and then modulated symbol streams aresubjected to analog precoding/beamforming in the multi-antennatransmitting processor 457 and provided from the transmitters 454 toeach antenna 452. Each transmitter 454 first converts a baseband symbolstream provided by the multi-antenna transmitting processor 457 into aradio frequency symbol stream, and then provides the radio frequencysymbol stream to the antenna 452.

In uplink (UL) transmission, the function of the gNB 410 is similar tothe receiving function of the UE 450 described in DL transmission. Eachreceiver 418 receives a radio frequency signal via a correspondingantenna 420, converts the received radio frequency signal into abaseband signal, and provides the baseband signal to the multi-antennareceiving processor 472 and the receiving processor 470. The receivingprocessor 470 and multi-antenna receiving processor 472 collectivelyprovide functions of the L1 layer. The controller/processor 475 providesfunctions of the L2 layer. The controller/processor 475 can be connectedwith the memory 476 that stores program code and data. The memory 476can be called a computer readable medium. In UL transmission, thecontroller/processor 475 provides de-multiplexing between a transportchannel and a logical channel, packet reassembling, decryption, headerdecompression, control signal processing so as to recover a higher-layerpacket from the UE 450. The higher-layer packet coming from thecontroller/processor 475 may be provided to the core network. Thecontroller/processor 475 can also perform error detection using ACKand/or NACK protocols to support HARQ operation.
